聚偏氟乙烯-六氟丙烯聚合物锂电隔膜的制备及形貌研究

摘要

选择涂敷机刮膜，分别采用两种制膜技术用聚偏氟乙烯-六氟丙烯（PVDF-HFP）树脂制备了锂电隔膜，并研究了PVDF-HFP的固含量、制膜温度、制膜方法和溶剂体系对于膜形貌的影响。%PVDF-HFP membrane for lithium ion battery was made by two different methods using automatic coating machine. The factors including PVDF-HFP content, the temperature, the different methods and the solvent system on membrane morphology were all discussed in this article.
